BACKGROUND

Changing diapers of a baby or “changing a baby” and other small children not yet toilet trained can be an incredibly frustrating task. Infants typically do not remain still during a diaper change presenting the parent, sibling, or other person the challenge of removing the diaper while simultaneously restraining the infant. Another challenge is that babies have a tendency to reach for the pelvic region upon diaper removal, creating an unpleasant and unsanitary environment. In addition, while changing the diaper, the individual may also want to apply medication, such as diaper rash lotion or medication. Thus it is desirable to limit the baby's arm motions. Most individuals do not have the dexterity to restrain the body and control the arm motions of a baby while simultaneously changing the diapers.

Accordingly there is a need for an apparatus which is adapted to elevate and position a baby's arms above the body and away from the pelvic area. Such an apparatus would also ideally help restrain the baby's body as well. An apparatus which restrains the baby's unwanted motions while keeping the baby comfortable, occupied and amused is highly desirable.
